Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) In the following detailed description, reference will be made to the attached drawings in which:

(2) FIG. 1 is a perspective view of a conventional air conditioning drain pan and condensate drain line; and

(3) FIG. 2 is a perspective view of a conventional air conditioning drain pan and condensate drain line having an air conditioning condensate drain line clean-out system of the present invention incorporated therein.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

(4) For purposes of describing the preferred embodiment, the terminology used in reference to the numbered accessories in the drawings is as follows: 1. air conditioning condensate drain line clean-out system, generally 2. drain pan 3. drain line 4. condenser 5. condensate 6. flushing line 7. water source 8. hot water heater 9. supply line 10. supply valve 11. timer 12. open end of drain line 13. drain valve 14. transformer 15. perpendicular section 16. cross-section

(5) With general reference to FIG. 1, a perspective view of a conventional air conditioning drain pan 2 and condensate drain line 3 is illustrated. Conventional air conditioning systems comprise a condenser 4 mounted over a drain pan 2 that collects condensate 5 that drips from the condenser 4. Condensate 5 collected in the drain pan 2 is directed toward a condensate drain line 3, which directs the condensate 5 to a sewer drain or outside of the structure in which the air conditioning system is installed. When the condensate drain line 3 becomes clogged with debris, the condensate 5 is unable to drain from the drain pan 2 and thus, collects in the drain pan 2 until the condensate 5 over flows and pours downward into the structure in which the air conditioning system is installed causing damage thereto.

(6) With general reference to FIG. 2, a perspective view of a conventional air conditioning drain pan 2 and condensate drain line 3 having an air conditioning condensate drain line clean-out system 1 of the present invention incorporated therein is illustrated. The air conditioner condensate drain line clean-out system 1 of the present invention may be integrated into a new air conditioning system or installed on an existing air conditioning system on the condensate drain line 3 thereof. The air conditioner condensate drain line clean-out system 1 comprises a flushing line 6 connected to a water source 7, such as a hot water heater 8, either directly or through a structure's plumbing system via a supply line 9 connected to the water source 7. A supply valve 10 allows preferably hot water to enter the condensate drain line 3 when the supply valve 10 is opened via a timer 11. As water enters the condensate drain line 3, the water travels in two directions, toward the drain pan 2 of the air conditioning system and toward an open end 12 of the condensate drain line 3 through which condensate 5 normally drains from. A drain valve 13 is located on the condensate drain line 3 subsequent to a point of connection between the flushing line 6 and the condensate drain line 3 to prevent backflow of water from the flushing line 6 into the drain pan 2 of the air conditioning system. The supply valve 10 and the drain valve 13 are controlled by a timer 11 that opens and closes the supply valve 10 and the drain valve 13 simultaneously so that when the supply valve 10 is opened, the drain valve 13 is closed and when the supply valve 10 is closed, the drain valve 13 is opened. The timer 11 is preferably supplied power via a 12 volt transformer 14. The timer 11 is preferably programmed to open and close the supply valve 10 and the drain valve 13 on a reoccurring basis to clean out the condensate drain line 3 prior to any blockages occurring.

(7) As illustrated herein, the condensate drain line 3 and flushing line 6 are in parallel positions connected by at least one perpendicular section 15 of the flushing line 6 and at least one cross-member 16, thereby creating a rectangular-shaped configuration between the condensate drain line 3 and flushing line 6. This configuration allows the system 1 to be installed in a confined area while providing support for the flushing line 6 to prevent loosening of any connections over time, which could result in flooding.

(8) It is to be understood that while a preferred embodiment of the invention is illustrated, it is not to be limited to the specific form or arrangement of parts herein described and shown. It will be apparent to those skilled in the art that various changes may be made without departing from the scope of the invention and the invention is not to be considered limited to what is shown and described in the specification and drawings.
